Rebuild index should validate entries in case of bucket selection strategy

[lvca]

In case the partitioned bucket selection strategy is selected (by default from v23.2.1 in case a unique index is defined), the rebuild of the index should check each record if belong to its bucket, based on the index key.

This is fundamental in the cases:

• the index is dropped and re-created and concurrent insertions happen
• the bucket selection strategy is modified and set to partitioned again
